Wa'alaikum assalam! Normal je baby umur sebulan lebih kentut banyak, tapi kalau berbau sangat menyau tu memang perlu tengok sikit, usually it means ada gas atau digestive issue kecil-kecilan je, especially if dia minum formula or baru introduce solids. A few of my mum friends mentioned their babies pun sama, tapi once they adjusted feeding schedule or tried burping better, the smell jadi kurang. Kalau dia okay je (active, minum well, tak ada tanda lain), likely nothing to worry about, but if he seems uncomfortable or you're worried, better check with your pediatrician to be safe! Camne dia lain-lain? Dia okay ke?
